FIELD OF THE INVENTION

The present invention relates to a textile treatment composition.

BACKGROUND OF THE INVENTION

Recent increasing awareness of aroma promotes development of a methodfor imparting and sustaining an aroma in a washed textile product bytreating the textile product with a textile treating agent such as adetergent and a fabric conditioner containing a fragrance having longlasting odor. In such a method, fragrance materials that are lipophilicand hardly volatile to transpire are generally used. These materialsinsufficiently release aromas and often have heavy aromas, and thusdetermine residual aroma tones. In contrast, hydrophilic and relativelyhydrophilic fragrance materials sufficiently release aromas and havewider variety of materials than lipophilic fragrance materials, and thusenable to design various aromas. However, these hydrophilic materialshave poor adsorption on textile, and thus provide weak aromas to atreated textile product with less long lasting odor. There is a strongdemand for a method of improving adsorption of a hydrophilic orrelatively hydrophilic fragrance material to increase a kind of residualaroma tone in textile.

Silicate ester compounds have been known to impart long lasting odor.Textile treatment compositions containing a silicate ester aredisclosed, for example, in JP-A54-59498, JP-A54-93006, JP-A55-127314,and JP-A2003-526644. JP-A2003-526644 particularly describes use of asilicate ester together with a fragrance composition.

SUMMARY OF THE INVENTION

The present invention provides a textile treatment composition,including components (a) and (b1) at a mass ratio of (a)/(b1)=98/2 to20/80:

(a) a compound represented by the formula (1):

(wherein, X represents —OH, —R1 (R1 represents an aliphatic hydrocarbongroup having 1 to 22 carbon atoms in total, which may be substitutedwith phenyl, hydroxy, or an alkoxy group) or —OR2 (R2 represents ahydrocarbon group having 6 to 22 carbon atoms); Y represents X or —OSi(X) 3; and n is an average number from 0 to 15; a plurality of X and aplurality of Y may be independently the same as or different from oneanother, provided that the compound has at least one —OR2 in amolecule),

(b1) a fragrance material having a logPow value not less than 3.0 andnot more than 5.0.

The present invention also provides a method for facilitating adsorptionof the component (b1) on a textile product, including contacting thecomposition with the textile product in water as a medium.

The present invention also provides a method of treating a textileproduct to impart an aroma, including conducting the step A and then thestep B or simultaneously conducting the steps A and B:

step A: treating a textile product with the composition

step B: subjecting the textile product to a heat treatment.

DETAILED DESCRIPTION OF THE INVENTION

JP-A54-59498, JP-A54-93006, JP-A55-127314, and JP-A2003-526644 describemethods using a silicate ester hydrolysate as a fragrance material. Inthese methods, long lasting odor is enhanced by gradual hydrolysation ofa silicate ester adsorbed on a textile product. These methods thus haveproblems that a fragrance material is limited as it must be an alcoholand no aroma is released without water. An alcohol material used forperfuming with a silicate ester is limited in view of the kind thereof.The kind of residual aroma on clothes cannot be increased by the methodof perfuming with a silicate ester alone. In addition, there is nosuggestion of an enhanced adsorption of a relatively hydrophilicfragrance material on a textile product by a specific silicate ester.

JP-A2003-526644 describes a specific example of combination use withother fragrance material. However, these methods use a silicate estercompound as a part of a fragrance. There is no suggestion of effect inthe case of mixing a relatively hydrophilic fragrance material with asilicate ester in a specific ratio.

Therefore, the present invention provides a textile treatmentcomposition that can increase adsorption of a fragrance, particularly arelatively hydrophilic fragrance on a textile product treated with atextile treating agent such as a detergent and a conditioner, canincrease a kind of residual aroma tone on the textile product, andallows various aromas to perfume strongly for a long time.

According to the present invention, adsorption of a fragrance,particularly a relatively hydrophilic fragrance on a textile product canbe increased, a kind of residual aroma on the textile product can beincreased, and the residual aroma can sustain strongly for a long time.

[Method for Facilitating Adsorption of the Component (b1) on Textile]

In the present invention, the method for facilitating adsorption of thecomponent (b1) on textile is conducted by contacting the textiletreatment composition of the present invention to a textile product inwater as a medium.

Preferred stage at which the textile treatment composition of thepresent invention is contacted with a textile product is a rinsing stepof a domestic washing process. The textile treatment composition ispreferably added to washing water in such amount that the total of thecomponents (a) and (b1) is 0.01 to 0.5 g, more preferably 0.02 to 0.3 g,and even more preferably 0.03 to 0.2 g to 1 kg of textile product.

Since the components (a) and (b) containing the component (b1) aregenerally water-insoluble compounds, these are preferably uniformlydissolved, dispersed, or emulsified in the rinse water. To achieve this,the component (d) plays an important role. In the present invention, thecomponent (d) presents in the rinse water together with the components(a) and (b) at a mass ratio of 1/20 to 20/1, preferably 1/15 to 15/1,and more preferably 1/10 to 10/1 to the total of the components (a) and(b). In the washing process, after the rinsing step at which the textiletreatment composition is contacted with a textile product, a generalwringing/drying step is conducted.

Examples of a method other than above include methods of adding thecomposition together with a detergent in a domestic washing process,directly spraying on a textile product with a spray, and applying with aroller and the like.

Another method for treating a textile product is described below.

[Method for Treating Textile]

The method for treating textile of the present invention is a methodincluding a step A of facilitating adsorption of the component (b1) on atextile product and a step B of performing a heat treatment. In otherwords, the method for treating textile of the present invention includesthe step A of treating a textile product with the textile treatmentcomposition containing the components (a) and (b1) and the step B ofheat-treating the textile product. In the preferred method, the step Ais performed and then the step B is performed, or the steps A and B aresimultaneously performed.

In the step A, examples of the method for treating a textile productwith the textile treatment composition include the following (i) to(iii).

(i) adding the textile treatment composition to washing or rinsing waterat a washing or rinsing stage in a washing process of textile

(ii) spraying the textile treatment composition to a textile productwith a trigger container and the like

(iii) contacting a carrier having the textile treatment composition witha textile product to be treated

When the method (i) is employed, a bath ratio (mass ratio ofwater/textile) is preferably 3 to 30, and more preferably 4 to 30. Inwashing with a drum type washing machine, the bath ratio is generallyautomatically determined according to a weight of laundry. It ispreferable to select washing or rinsing conditions for effectiveadsorption of the textile treatment composition on a textile product inconsideration of the bath ratio and the like. In this method, thetextile treatment composition is preferably used in an amount of 0.005to 15.0 g, and more preferably 0.05 to 10.0 g per 1 kg of textileproduct. An additive amount of the textile treatment composition towater is preferably 0.001 to 1000 ppm and more preferably 0.01 to 100ppm.

In the step B, preferred examples of the method for heat-treating thetextile product treated with the textile treatment composition includemethods of directly contacting with a heat source (contact heatingmethod) and of heating a textile product via a medium such as the airwithout contacting with a heat source (non-contact heating method).

As the heat source in the contact heating method, a heatable hardsurface such as an iron and a press can be used. A surface temperatureof a contacting face is preferably 80 to 250° C., more preferably 90 to240° C., and even more preferably 100 to 230° C. A contacting face maybe contacted via a damp cloth. A heat treatment time is, which ischanged with a given temperature, about five seconds to 5 minutes.

Examples of the non-contact heating method include heating under aheating atmosphere. A heating dryer, a heating washer-dryer, and thelike can be used. A temperature of the heating atmosphere is preferably50 to 120° C., more preferably 50 to 110° C., and even more preferably50 to 100° C. A heat treating time, which largely depends on atemperature of the heating atmosphere or a function of a heating dryeror a heating washer-dryer or the like, is about 5 to 400 minutes.

In simultaneously conducting the method (iii) of the step A and the stepB, the step A and the step B can be simultaneously conducted under ahigh temperature atmosphere by placing a carrier having the textiletreatment composition containing the components (a) and (b1) togetherwith a textile product under a high temperature atmosphere. Further, thestep A and the step B can be simultaneously can be conducted or bycontacting the carrier having the textile treatment composition with atextile product under ambient atmosphere and heating to change theatmosphere to a high temperature atmosphere. In latter case, the carrierhaving the textile treatment composition of the present invention and atextile product are preferably stirred so as to be contacted each otherat high frequency. A textile product contacted with the carrier havingthe textile treatment composition of the present invention preferablycontains water, because the component (b1) is adsorbed on the textileproduct via water as a medium. Water contained in the textile product ispreferably 30 to 300% by mass, more preferably 30 to 200% by mass, evenmore preferably 30 to 150% by mass, and even more preferably 30 to 100%by mass of the textile product.

<Method of Treatment with Textile Treatment Composition and Measurementof an Adsorption Rate of Fragrance Material>

(1) Pretreatment

24 cotton towels were previously washed with a Hitachi automatic washingmachine NW-6CY using a commercially available weak-alkali detergent(Attack, Kao Corporation) five times and dried in a room to removeexcess agents (detergent concentration: 0.0667% by mass, tap water used:47 L, water temperature: 20° C., washing: 10 minutes, rinsing in storedwater: two times).

(2) Treatment of Textile with a Treatment Composition

In a National electric bucket N-BK2-A, a textile treatment compositionwas dissolved in 5 L of tap water so as to be 10 g of the compositionper 1.0 kg of fabric (preparation of a treatment bath). Two cottontowels pretreated as described above were soaked therein for 5 minutes,and stirred for treatment. The soaked towels were transferred to adomestic two-tub washing machine, and dewatered for 1 minute.

An adsorption rate of fragrance material is determined from an amount offragrance in a treatment bath before treatment (x) and an amount aftertreatment (y) by deducting (y) from (x) to meet an absorbed amount ontowels [(x)−(y)] and calculating a rate (percent) of the absorbed amountto the amount before treatment (x), that is, [(x)−(y)]/(x)×100. Theresults are shown in Table 2. In measuring an amount of fragrance in atreatment bath before and after treatment, the following liquidchromatography unit was used.
